Description
Aus Draht gewickelte Schraubenfeder für Ventile von Explosionsmotoren. Die Erfindung betrifft eine aus Draht o. dgl. gewickelte Schraubenfeder für Ventile von Explosionsmotoren, deren Neuerung darin liegt; daß sie aus meh-eren nebeneinanderliegenden und miteinander verbundenen Drähten besteht. Federn dieser Art stellen sich billiger und sind betriebssicherer als die bekannten eindrähtigen Federn, was besonders für@Flugzeugmotore von Yichtigkeit ist.Coil spring wound from wire for valves of explosion engines. The invention relates to a coil spring for valves wound from wire or the like of explosion engines, the innovation of which lies in this; that they are made up of several adjacent and interconnected wires. Springs of this kind are cheaper and are more reliable than the well-known single-wire springs, which is especially true for @ aircraft engines is of importance.
Die Zeichnung veranschaulicht beispielsweise eine Ausführungsform der Feder mit zwei D.ähten in Abb. x in einer Seitenansicht und in Abb. a in einer Draufsicht.For example, the drawing illustrates one embodiment the spring with two threads in Fig. x in a side view and in Fig. a in one Top view.
Die von der Stützfläche P ausgehenden Drähte F1, F2 werden nach Bildung einer gewissen Anzahl von Windungen S1 nach der Wirkungsstelle geführt, die sie kreisförmig einschließen, und von wo sie an der Seite zurückkehren, um eine andere Gruppe von Windungen S2 zu bilden, worauf sie schließlich an der Stützfläche endigen. Die Windungen S2 können verschiedenen Durchmesser haben und entweder über einen Zylinder oder einen Kegel gewickelt werden. Die Drähte werden unter sich entweder durch Hülsen B, Schweißung oder Lötung zusammengehalten. Anschläge A dienen als Führung. Die Hauptvorteile dieser Art Schraubenfeder liegen in der bereits erwähnten beträchtlichen Vergrößerung der Sicherheit, da die Feder ihre Wirkung mit den verbleibenden Drähten fortsetzt, selbst wenn die eine oder andere in ihrer Federkraft nachlassen oder zerbrechen sollte, weiter in der Möglichkeit, die aktiven Windungen von der Antriebsstelle fernzuhalten, um sie entweder vor einer Wärmewirkung oder Behinderung anderer Teile oder jeder anderen Störung zu bewahren, sowie in der Mög'ichkeit, den zwischen dem Stützpunkt und dem Wirkungspunkt erforderlichen Raum auf das für den Hub erforderliche gerirg3te Maß zu beschränken; endlich auch in der Verwendungsmöglichkeit von Drähten normaler Durchmesser für eine starke Beanspruchung, da die Kraft der Feder der Zahl der Drähte proportional ist.The wires F1, F2 emanating from the support surface P are after formation a certain number of turns S1 after the point of action that they lead enclose circularly, and from where they return to the side to another Form group of turns S2, whereupon they finally end at the support surface. The turns S2 can have different diameters and either one Cylinder or a cone. The wires are going under either held together by sleeves B, welding or soldering. Stops A serve as Guide. The main advantages of this type of coil spring reside in that already mentioned considerable increase in safety, since the spring takes its effect with the remaining ones Wires continues, even if one or the other in their spring force slacken or should break, further in the possibility of the active turns of the Keep drive point away to protect it from either a thermal effect or obstruction to preserve other parts or any other disturbance, as well as in the possibility of the space required between the base and the point of action on the for to limit the stroke required reduced amount; finally also in the possibility of use of wires of normal diameter for heavy use, as the force of the Spring is proportional to the number of wires.
